Description
- The present invention relates to the production of articles having a shape which is not flat, more specifically slightly curved, from a mix consisting of granulated inorganic materials and hardening resins as binders.
- Articles obtained from a mix consisting of granulated natural stone and/or stone-like and/or ceramic materials and hardening resins are well known in the technical literature - see in particular the patents
US-A-4,698,010 and5,264,168 . Variants of these articles also exist, these being characterized by the additional use of reinforcing elements, for example metal and/or glass fibre elements - see, among other publications, the patentsUS-A-5,670,007 and6,205,727 as well as the patent applicationWO-A-03,035,994 US-A-3773447 discloses a method for producing an article, with a non-flat shape which has a radii of curvature of about 15 cm or more in , comprising the following steps: - preparing a mix comprising granulated inorganic materials able to be hardened by means of cross-linking,
- preparing a flat forming support, protected by an anti-adhesive sheet
- spreading the mix over said forming support
- hardening the shaped panel so as to obtain the curved panel as desired.
- These articles always have a flat shape, both in the case of sheets and panels, where the thickness is much smaller than the other two dimensions, and in the case of parallelepiped blocks, i.e. when all three dimensions of the articles are of the same order of magnitude. Thus, although widely found on the world markets, these articles are not universally used, as instead would be desirable because of their excellent mechanical properties and other characteristics.
- The main object of the invention is to provide an industrial method which allows the production of articles, in particular sheets and panels, having a shape which is slightly curved (i.e. with a radius of curvature greater than about 15 cm).
- This object and other objects are achieved by a method having the characteristic features of a first set of the following claims.
- Another object of the invention is to provide, among the many articles which may be produced with this method, panels with a curved shape which are used to line the metallic inner surfaces of mixing machines inside which mixes comprising abrasive ingredients are processed.
- This object, together with others, are achieved by articles having the characteristic features of a second set of the following claims.
- The following description will be useful for illustrating more clearly characteristic features and advantages of the invention, said description being provided solely by way of a non-exclusive example with reference to the accompanying drawings in which:
-
Fig. 1 is a schematic view of an article produced with the method according to the invention, the article being shown in a three-dimensional view from above; -
Fig. 2 shows the article according toFig. 1 in the state it assumes during the hardening step which forms part of the method according to the invention; -
Fig. 3 shows - along a vertically sectioned plane - a mixing machine in which a plurality of articles according toFigs. 1 and 2 are used as a lining; -
Fig. 4 shows a cross-section, on a larger scale, along the line IV-IV ofFig. 3 . - In the following description reference will be made to the production of curved panels for lining the inner surfaces of the walls of mixing machines used for processing mixes containing ingredients with abrasive properties. This description nevertheless is provided by way of an example and is not exclusive since the articles produced with the method according to the invention may, for example, also be used in the building sector (for lining internal or external walls or for covering roofs) as well as in durable consumer goods.
- As shown in
Fig. 1 , the article to be produced, which is denoted overall by thereference number 100, comprises twofaces rectangular side faces reference number 150 can be seen. - According to the invention, the method for producing the
article 100 comprises the following steps: - I) preparing a mix comprising granulated inorganic materials (for example stone and/or stone-like and/or ceramic materials) and an epoxy resin, which can be hardened by means of crosslinking. This type of resin is preferable to polyester resins (commonly used to produce conventional flat articles) since they harden with a very small degree of shrinkage and the dangers of distortion of the article are avoided;
- II) preparing a flat forming support, protected by an anti-adhesive sheet, for example as explained in the patent
US-A-5,928,585 . The term "anti-adhesive sheet", used here, comprises both a sheet made with a single non-adhesive material and a sheet made with the same type of materials used for manufacturing the forming support (for example rubber) and protected with a non-adhesive and/or separating film; - III) spreading the mix over said forming support;
- IV) extending over the free surface of the mix a second sheet of anti-adhesive material, of the same type as that used to protect the forming support;
- V) compacting the mix by means of vacuum vibrocompression so as to obtain a panel having the consistency of plasticine, namely soft but sufficiently compact such that it does not fold during the following step of this method;
- VI) transferring the mix thus compacted (together with the two sheets of anti-adhesive material) onto a rigid support with a curved shape;
Fig. 2 shows apanel 100A of shaped mix which is arranged between the twosheets surface 350 of therigid support 300; thesurface 350 has the same radius of curvature R1 as theface 110 of the finished article (as already mentioned hereinabove with reference toFig. 1 ) and may be not only concave as shown inFig. 2 , but also convex or undulated, i.e. alternately concave and convex; - VII) keeping at room temperature the
panel 100A of shaped mix on thesupport 300 until hardened; - VIII) in order to complete (if necessary) cross-linking of the epoxy resin, heating the hardened panel to about 40°C (i.e. to a temperature slightly higher than room temperature);
- IX) removing the two
sheets - X) trimming the edges of the hardened panel, for example using a diamondcoated disk, so as to obtain the finished
article 100. - In the case where the use of the article thus produced requires a high impact strength, the step III) may envisage spreading, onto the flat forming support, two superimposed layers of mix with a reinforcing layer in between, for example a glass fibre or metal mesh or mat, for example a steel mesh.
- As already mentioned,
Figs. 3 and 4 show an example of use of articles made using the method described. The figures relate to a vertical-axis mixing machine for processing mixes containing one or more ingredients with abrasive properties, which comprises acylindrical container 10 and amotor 20 for operating amixing unit 30 comprising a plurality ofvertical blades 40. Further details regarding this type of machine may be found in an Italian patent application filed on the same date by the same Applicant. - The
container 10 comprises abottom wall 12 havingfeet 14 for resting on the ground P and aside wall 16. In a manner known per se, thebottom wall 12 is divided into a fixed part and a movable part or shutter (not shown) in the form of a circle segment which, in the open position, uncovers an aperture (also not shown) for discharging the mix at the end of processing. - As shown in
Fig. 4 , theside wall 16 of thecontainer 10 comprises an outer shell 161 and an inner shell 162 joined together byradial ribs 163. These parts are made of metal, for example steel. The inner shell 162 is lined internally withcurved panels 164 which are manufactured using the method described above. Thecurved panels 164 are fixed tosteel sheets 166 provided with stud bolts (not shown) which are butt-welded onto them and which allow them to be mechanically fixed to the shell 162 in an easy and rapidly removable manner. Alternatively, thecurved panels 164 are glued, for example by means of silicone adhesive, directly to the inner shell 162. - It has been shown in tests that the use of the
panels 164, in this case made of granulated quartz (light-coloured/transparent material with a hardness factor of about 7 Mohs) or, even better, alumina or corundum of the white type (light-coloured/transparent material with a very high hardness factor of about 9 Mohs) which have a very long working life (i.e. about 6-8 months of two working shifts), produces the following advantages: - it prevents the release of metal particles detached, as a result of the abrasion exerted by the hard aggregates, from the inner shell 162 of the
side wall 16 of thecontainer 10; - since the colour of the mix being processed is not contaminated, the frequency of the maintenance carried out on the said
container 10 is reduced; and - cleaning of the
side wall 16 whenever the mix is changed is much easier since the hardness of thepanels 164 limits the appearance of scratches to which the mix could adhere. - In short, owing to the use of the
sheets 164 inside thecontainer 10, the productive efficiency of the mixing machine is increased. - In addition to the hard stone materials considered above, other inorganic materials may be used in the method according to the present invention. For example, if the articles to be produced must be extremely hard and the colour is not of importance for their specific use, carborundum may be used. Vice versa, if the applicational requirements of the articles are less demanding, granulated ceramic materials may be used.
